ARCHIBALD A. MALEY, OF NEW YORK, N. Y.

REVERSIBLE ENVELOPE.

SPECIFICATION forming part of Letters Patent No. 437,705, dated October 7, 1890.

Application filed May 23,1890- Serial No. 352,870. (No model.)

1'0 on whom it may concern:

Be it known that I, ARCHIBALD A. MALEY, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Reversible Envelopes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which Figure 1 represents the blank form with the tongues and slots cut in the various parts as a means of securing the envelope after it is folded. Fig. 2 represents the envelope partly folded. Fig. 3 represents the envelope folded.

This invention relates to envelopes generally, but more particularly to reversible envelopes adapted to carry sample-goods and its object is to furnish an envelope the flaps of which may be folded with either side out, and when so folded may be locked by means of tongues and slots provided for the purpose in such a manner as to preclude the possibility of the contents slipping out or of the flaps accidentally becoming unlocked.

To this end it consists in certain novel features of construction and arrangements of the tongues and slots, which will hereinafter more fully appear.

The body portionAmay be provided on one side with the address of the sender and the return-stamp, the opposite side being left blank for the address of the sendee, and said body portion A is provided with the usual end and side flaps a cl 5 h, somewhat larger than those used on the ordinary sealed envelope. In the end flap a are four slots, as shown, two of which register with similar slots in the flap d, and the remaining two are adapted to register with and receive opposed tongues c e on the flap d. The two side flaps are each provided with two opposed tongues f g and z'j, respectively, adapted to enter the registering slots in the end flaps a d.

In folding the envelope the leaf or flap ais first folded over on the square central portion A. The leaf (1 is then folded over and the tongue 0 is inserted in the slot 0 and the tongue 6 is inserted in the slot 6', when the envelope will appear as shown in Fig. 2. Next the side leaf 1) is folded over and the tongue f is inserted in the slot f and the tongue ginserted in the slot 9. The remaining leaf h is then folded over and the tongue t' is inserted in the slot f and the tonguej insertedin the slot 9, when the envelope will appear as shown in Fig. 3.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a reversible envelope, the combination, with the body A, of the end flaps having each two parallel slots and the side flaps having each two opposed tongues, the slots of one flap adapted to register with the slots of the opposedflaps, and each set of registering slots located to register with and receive two tongues, one on each of the opposite flaps, substantially as and for the purposes set forth.

2. In a reversible envelope, the combination, with the centralbodyA, of two side flapshaving each an outwardly-extending tongue on the edge thereof and an inwardly extending tongue adapted to work through said flap, an end flap provided with a similar set of said tongues adapted to engage slots in the opposite flaps, and two registering slots in each of the end flaps, adapted to register with and receive the opposite tongues on the side flaps, substantially as and for the purposes described.

In testimony that I claim the foregoing improvement in reversible envelopes, as above described, I have hereunto set my hand this 8th day of May, 1890.

ARCHIBALD A. MALEY.
